I've noticed something similar intermittently however if that is cause for a replacement to the 2018 model then I would absolutely jump on that.
So, in answer to your question, I originally didn't now there was the option to replace the 900E with a 900F set UNTIL the wonderful post by sneals2000. Now - two things, here. It really depends on how much the frame jumping is affecting your viewing (I think it's more noticeable on larger sets like my 75" 900E versus my 49" 900E) and who you bought your TV from and the process of getting this documented and replaced. If you have a great panel, now, that is a consideration, as well. (Hence my having my Sony Dealer plug the replacement 900F in and view it prior to having it installed to replace my current set.
I purchased my Sony 75" 900E back in July, 2017, from an authorized Sony Dealer here in Colorado. Since it is a large set, I wanted delivery and setup plus installation on my wall in my man cave. I used my Chase Freedom Credit Card to "match" online pricing (hence a $500 credit) and to obtain the best of both worlds by having the expertise of a local Sony Authorized Dealer and a great price.
I had noticed the frame jumping primarily on live sports. College football, especially, and from many Colorado Buffalo games. It didn't happen that often and it seemed like when it did, it would carry on for awhile. My best friend's daughter also noticed it when we watched last year's CU/CSU game. For regular viewing of cable channels like CNN or even major broadcast channels and series like the "Blacklist," - I honestly didn't see much frame jumping at all. And never on streaming from Amazon Prime or Netflix or Google Play Movies.
So - if it's an option for you AND the process isn't too difficult AND you can verify that you're getting a good panel - - I'd say go for it.
Differences between the Sony 900F and Sony 900E -
2018 Model (F) versus 2017 Model (E)
X1 Extreme Chip (Dolby Vision capable) versus Extreme Chip (No Dolby Vision)
6X Contrast (F) versus 5X Contrast (E)
Black Area Blinking (F) versus Black Frame Insertion (E)
The last difference is interesting in that out of all the Sony Models (Z9D, X940E, X900F & X900E) - the "F" model is the only one to have this technology where the screen does not lose brightness from black frame changes/transition (I probably am not describing this exactly but that's the best way I can explain. ) And, I think this also affects the "frame jumping" issue. I'm not sure if this is a "software fix" or hardware enhancement or a combination of the two.
At any rate - - within a couple of weeks, I'll have the 900F 75" replacement and it will be interesting to see if the frame jumping is gone and what Dolby Vision looks like. I'm keeping my Sony 900E 49" set as I really don't notice many problems with it. And - - I purchased this set from "Best Buy," and I'm more than a year out on the Sony Manufacturer's Warranty for the 49" set.
