1) Define "invert". Even in 2.8, you have "INert" and "Value invert"
2) Working on a gamma corrected image or on a linear light one?
3) I don't see much of a highpass filter in the technique shown (with just a "Normal" mode). Grain merge is better
On the whole, 2.8 works directly on the gamma-corrected values (with a few exceptions, and I expect Color->Invert to be one). In 2.10 it works mostly on the linear values and if you want something that looks like the gamma-corrected processing you use the legacy modes.
