I am wondering if I am getting a lot of ceiling reflection from my left and right speakers and it's drowning out or blending with the Atmos speakers' output.
If I play a couple of the Dolby Atmos demo videos (like the one with the rain and falling leaf) I can hear the Atmos effect more noticeably. I am theorizing that it may be because they tend to be quieter overall scene so the fronts aren't blasting out sound to compete with or drown out the overhead speakers.
So true! And it's either the fault of or to the credit of the Sound mix.
So my question is how do I test if this is indeed the case and then how do I test possible solutions? I imagine if I am right the solution would be sound treatment on the ceiling but how much and where? And how can I test the results without marring my ceiling in the process?
The solution really doesn't require as much of a "Test" as it does a specific "action" to take.
You were "probably" hearing more imaging from your Surrounds than from the Atmos channels. But not because of Reflections, which would serve to muddy the sound enough to be noticeable. Certainly an effective deadening of the Ceiling would eliminate reflection from contention. As I see things, the RSL C34E speakers can deliver impressive Atmos, both by directing AND dispersing the content where it is best suited, so you issue lies elsewhere. That being using the RSL C34E's to best effect.

Be aware though there have recently been a score of bad Atmos (well,not bad,but very low volume) blurays especially from Disney.. Proper atmos soundtracks are the new Tarzan movie 2016, Jupiter Ascending and the John Wick movies..
Be also aware,most of the time the overheads deliver atmosphere and background sounds like echo in a theater or busy street noises.. The whole idea of atmos is to "be in the center".. Directional effects like planes or helicopters overhead are not that common.
Atmos is the sole reason i upgraded my home theater and i am not dissapointed.
has it exactly right. Atmos is exactly what Atmos is intended to be. Not at all like early Surround channel effects. Who remembers when Surround channels were only a small percentage as powered as the Mains? And there were always smaller and more cheaply made? But why? Because to make them even noticeable they had to be efficient enough to play at higher volumes with less power. That is starting to address the OPs issue...but in reverse.

I figured for the pretty cheap price it was worth it to play with Atmos (I have a 5.2.4 setup) since the LX503 was cheaper than a few of the 5.2.2 AVRs and the difference between $40 for two height speakers and $80 for four height speakers was pretty much nothing. I do like it better no-Atmos, but I expected a bit more than what I have gotten so far.
Gaming, on the other had, is pretty cool (only played Rise of the Tomb Raider [on the XB1X] so far, but the opening mountain scene sounded great). The Star Wars Battlefront Atmos demo was also great. I need to download that and play it again (the sound design in that game was awesome).
The above is something I have discussed with several members...that even inexpensive Speakers placed at least semi-correctly created appreciable Atmos effect....certainly a distinct improvement over "no Atmos at all. But a current that ran through everyone's situation was perceived volume. Just as with early Surround adopters (...especially those with "effect" channels....), while the content was there...it could not be heard distinctly enough....or at least as desired. So VOLUME was the answer. Calibrating Atmos to a select signal just doesn't work very practically. While it does blend the frequency response to a room's acoustics, that signal does not accurately represent actual content. And THAT has always been the plague that has beset many....poorly heard content. That alone has always driven many to discount surround effects, and all that has created resistance to every step along the way to advanced multi-channel formats, all through 5.1 - 6.1 - 7.1 ...and beyond. Well that and the resulting price bump.

Of the three Dolby staff conducted presentations I've attended the fact that this new feature provided an opportunity for dealers and installers to go back to their existing client base with something new to sell was always emphasized in the first few minutes of the talk. Not how transforming the audio experience was going to be.
OMG...a voice of reason! Absolutely, CEDIA and everything about it is focused on urging Dealer / Installers to push new...and expensive technology on both post and present Customers. Now for me, I have been dealing with surround sound since it's earliest adoption (pre-1980) because it suited the system designs I was / am involved with. Designs that required a higher power curve than almost anything else....but in doing so always helped deliver surround-oriented content with more presence. These days, Atmos can be drop-dead spectacular depending upon content...and with conventions speakers as well.
So my best advice? It's the same as Tsunamijhoe
's. Turn up the Atmos channels on those RSL C34E's!
But wait! You mentioned your Ceilings are only 8' and the room's width is 14'. It would also seem that with such a limited distance involved that the RSL C34E's can't really disperse the Atmos content widely enough, so perhaps they are "spotlighting" low volume content more than they should, outside of the ideal seating locations? Angled Drivers can be a double-edged sword...they can be great to direct imagery....but they tend to minimize the ideal listening area. They work best in higher ceilings in larger rooms where distance requires more direction-ality but also helps with dispersion.
I have myself used the RSL C34E's when I had to, but not as a last resort as much as a viable and extremely acceptable choice. They are as far as I'm concerned the singular best value in a In-Ceiling driver that can be applied to Atmos applications. However......an 8' Ceiling is a consideration, and since there is no supplied positioning description (..and with the size Holes required of the RSL C34E's relocation is not a viable choice....) increasing Volume is the most logical and sensible solution.

..........what he said.
