Assuming you are refering to preview #8.
I can't remember which post or person analyzed the image, but it has already been concluded to be the HOTs home. Specifically, Josy's room. So, my guess is that they are two distinct events. Thus, Josy should still potentially be present Maya during the Thanksgiving party.
It was me, probably, we also had an argument with several people about where Josy's scene takes place.
I'm lasy now to find the explanation text for each number, but here it is:
Major arguments - the same pillowcase and mattress, no one will drag them into the tent, it's just stupid, and in a tent of the size that we see, no one uses them. Usually sleeping bags or something compact are used. Pink wall(s), bed metal bar(s) and Josy's hair - we already seen her in that camping trip preview - she was with her usual ponytail. I can accept and explain the new hairstyle at the party and ponytail in bed scene but not vise versa.
Now regarding latest preview
Regarding Maya... particular haircut can significantly change person apperiance and perception. Including "age" perception things. But honestly most of Maya critics and sceptics just don't like her initially and just constantly search for any argument and negative against her.
DPC through the timelapse of development improved almost all characters in the way they look, as well as rendering complexity and quality, most of S1 images are quite "flat" and poor in terms of lighting and shadowing. Then with each episode he improved models more and more. Tbh if you return her old haircut, makeup and make simpler lighting (less shadows etc), she will look identical as she was in previous episodes.
It's almost confirmed that DPC uses PS (or some similar soft) batch postprocessing. I heavily doubt that DAZ may produce such "dark" renders as we can seen it in the latest episodes (7-8-9). He don't have extra time to mess with different settings each time, so, probably he use a few presets here and there. Only this can explain why Josy skin changes color whithin one episode several times (EP7 is the best showcase). Probably that last episodes was the time when he started to actively use the postprocessing. And EP7 was just the beginning and it can explain such imperfections. The result is more consistent and stable in EP8 and EP9. I hope it will only be better in EP10 and further. DPC is a perfectionist in most places and it's mean a lot.
Look at this:
Josy's scene in EP8 (Jym). The upper image where I added a lot of lightness in PS and reduced the contrast and reduced saturation and color vibrance, the bottom is original one. Now tell me he don't use the postprocess.
He probably adds a sharpness and uses some other tricks, because sometimes skin details are insane and extreme. Now look at the most of fanart, even made by very skilled DAZ artists.
Finally, latest preview:
You guys compare images and skin tones in outside scenes under the "sun" and the inner scenes with artificial lighting. Any beginner in photography or other artist working with lighting will tell you that this makes a huge difference, and principally gives different conditions and expectations for a final result.
