Great review but instead of sending back every tv right away that you test
keep them for awhile and compare them to the tvs you review
side by side comparisions says more about the tv.
for example we could watch those wrong colors on the oled in HDR10 mode if you had the Pana DX902 up at the same time.
now we dont know how off they really are compared to where they should be.
we could also compared how much dimmer the highlights was on the OLED in hdr compared to the Pana.
we know what 650nits looks like but how does they stand to 1300nits?
more side by side comparisions thanks and also comparisions against a reference monitor
people seems to forget fast how those 5% and 100% slides should look on a reference tv
they look ok here but still they are not close to the uniformity of some other tvs.
i dont know what camera you have if its an DSLR but to get rid of the moire patterns use a higher F/stop or manually adjust focus.
the problem is that the camera picks up to much sharpness.
manually set focus slight out of range will reduce the moire patterns
as for photos with color accuracy from the tvs
set white ballance to 6500K on the DSLR
then you get photos that shows the exact colors that the tv shows irl
