Yes, massive self-latinisation.
What Herbigny (especially), AMM, asianpilgrim and Pavel Ivanovich said. Pavel has described something I've noticed for some time, the self-latinisation of shortening the sticharion so it's more like a large Roman cotta.
Herbigny has described most of the Greek Catholic world outside of the Internet.
Thanks for the link to the page on the Old Believers.
Here is the chapel with an iconostasis on the wall:
