color shift on 2nd pass if resolution larger then 1024

thanks for your work. it's a great lora for ltx.
But I do get a color shift. the first pass is good. In my case I'm using the dev model with LTXVScheduler 18-30 steps.
that pass looks good. but on the second pass, there is a strong color shift. like the video gets very pale/brownish.
This happens only for initial resolutions above 1024 in width.
This also occours if switched to a distill 1st pass.

I do know this effect if using general ltx2.3 i2v if the 1st pass is e.g. 2k then 4k 2nd pass.
In case with the cameraman v2 lora it seems to occur even on lower resolutions.

any idea?

greetings,
sebastian

the 2nd pass is just for upscaling. you can try any other upscaling method
