Will X-T5 video quality be worse than X-T3/4?

Bumping up this topic as I am quite interested to hear the feedback as well as I am hesitating between the two for my B-Cam for light traveling with say 60/40 photo/video split.

Essentially the 40Mpx is a nice upgrade, along with better AF/IBIS for the X-T5 but I will dearly miss the flip screen and don't necessarily need to print large or crop that often.

I did some research and maths and would like to see how the two cameras compare for video especially.

From my understanding,

For 4k up to 30p, the X-T4 already oversamples from 6.2k without naming it "4KHQ" and that is without a crop versus the X-T5 which crops at 1.23x giving the used sensor the size of a (slightly larger) MFT sensor.

For 4k60p, I am not entirely sure if Fuji uses Line Skipping or Oversampling but from Gerald Undone's review of the X-H2 (which might be comparable to the X-T5 process), the camera line skips from 6.7k sensor size (1.74x total crop factor) which also affects dynamic range and seems to crush the blacks by almost 1-2 stops. The sensor size for the X-T4 is very much the same for 4k60p but would cover only 5.3k with its smaller resolution.

Do you guys know if that 4k60p from the X-T4 is line skipped or oversampled ? Is this loss of dynamic range/crushed blacks also an issue there? I reckon if it is instead oversampled then the X-T4 would be better than the X-T5 for video IQ (assuming similar sensor tech and the fact that not everybody needs 6.2k)

Happy to hear your thoughts there!

As was already answered in your other post, yes the xt5 line skips the 4k60. All those extra pixels for photos don't come without a cost for video. There's a balance that has to be achieved between line skipping, cropping, pixel binning, over sampling, rolling shutter and moire within the limits of the processor when the fps is increased. The XT4 will remain the B cam to my XH2s until I cough up the funds for a second XH2s as the xt5 doesn't represent any real benefit for video.
