I was under the impression that the HT3550 had some form of dynamic tone mapping. Is that not the case?
I'd also like better input lag since I am 60/40 movies/games but I'm willing to stick it out with BenQ a couple more years due to the great price/value ratio. I would like love to try out a mid-level Epson but I've always had DLP projectors and the reports of lack of sharpness scare me.

Screen brightness is a subjective measure, so the HT3550 could be bright enough on ECO on a 120" screen.
No projector has dynamic tone mapping except for latest JVC NX series.
Some of the external options for dynamic are Madvr Envy or madvr on a htpc. Still a static tone mapping option, but some users have Panasonic UB420/820/9000 (last two have Dolby Vision) which can improve HDR PQ on even the 5050UB.
That room makes possible for a projector with better black level/contrast. Unfortunately 3LCD on Epsons are not as sharp as some 4K DLP's, but it's a very subjective topic. UB series (5xxx/6xxx) have different components from the HC3xxx/2xxx series including better lenses which help with sharpness. The better contrast in the UB series also helps with contrast.
Sharpness is also affected by the source, original resolution, etc.
How far away is the seating distance?
Epsons also generally have ~mid 20ms lag in both 4K and 1080p. It's unclear what the lag for 4K projectors is for a 4K source.
IMO a projector with good black level/contrast like the 5050UB will do much better than a 4K DLP picture quality wise. A 5040UB refurb can be had at a much lower price, but only has a 10GB HDMI, which means that for gaming or some streaming services that require 4K HDR 60Hz the bit depth requires to be dropped to 8bit from 10. This can be done with a PC/other device or a HDfury Linker or similar.
The HT5550 has a native contrast of ~700:1, while the UB series is ~4000:1. The HT5550 achieves better black level (still not as good as the UB's) via an iris, which can cause pumping artifacts, extra noise, and lowers the brightness of the entire image.
DLP has better motion handling than 3LCD< but 3LCD is still ok:
