100% so many variables to consider

more light, more detail and the most important difference a record-breaking sharpness now seems to look out the window.
I am very happy with the change
Also, in most cases, the cost to change from 760 to 870 is LARGE and the differences (to me) are not worth the extra cash.

@hasta666 I would wait until September as the 760 is due for update/replacement then, if Sony remain historically consistent that is.

No new projectors from Sony and JVC announced. Rumours have it there will be no upgrades/new models this year from both of them.

Especially since JVC was struggling so hard with their NX line-up.

If that is the case then I will be surprised, but on the other hand, that might explain the major firmware update for the 760 that we all thought would not happen.

I am all for supporting these things for longer with feature and performance updates! They have the processing chops for auto tone mapping I reckon as well, so I would like to see that added on the 760 and 870!

I would love to see an added Auto tone map but emailing some people who are close to Sony they have responded with metadata at most time being incorrect they don't see no point in putting in adding that feature in. I personally believe that the metadata on these discs will get better and more accurate in the future. I guess time will tell.

I have to mention that I have the zone based automatic convergence correction deactivated (in the service menu). Here IMO less is more. Furthermore I hardly use any lense shift. If you check the R. Masciola resolution patterns (or those on the new Spears&Munsil UHD evaluation disk) any artifacts by the RC and sharpness sliders become quite obvious.

So for me the ARC-F lense is certainly useful for a very big screen and if you you are using a lot of lense shift. The better the lense the less chromatic aberration. However I think that the advantage of the VW995 ARC-F lense is partially hampered by the chroma upsampling with the Sony. I note a half a pixel shift between luma and chroma judged by the S&M UHD HDR benchmark disk. Despite the excellent lense the full and perfect UHD resolution is not achieved due to the limitations of the upscaling process. I hope that future chips will be able to allow full 10 bit chroma processing which seems just not to be the case now.

I have turn my RC off on my 870Es no need for it too be honest image looks great. I know with the 870es they have upgraded the processing board with the link I provided earlier down the posts.

Sony processing board

Sony's new Motionflow and 12-bit imaging processing are powered on a newly designed circuit board within its 2018 projector products.
I have the spears and munsil UHD disk will have to check.

Which in turn were upgraded to match the 760. The 270, 570, 760 and 870 all have the same board.
