The style is irrelevant.
Did Starkiller Base have a stupid ring around it when it exploded? Nope.
Was there a scene on Cloud City depicting the SE windows instead of the OT windowless hallways? Nope.
Was there a Sarlacc on Jakku with a stupid beak? Nope.
Has Hayden Christensen showed up as the ghost of Anakin? Nope.
Nothing depicted in the post-Disney films requires the SE versions of the OT in order to work. Therefore, either version of the OT could be canon at this point, regardless of which version is “officially” canon.
I don’t get your logic. Disney has said the SEs are canon, therefore they are canon to the ST.
Oh another one could be- Ewan McGregor was in TFA, and he played the Master of SE Anakin.
