Nice, I'll test it. From what I've read, Kodi tries to find closest resolution in the skin, if it is not there, it uses next lower one.

This gets the first resolution with corresponding aspect ratio?

Yes and no. Yes because it gets current used aspect ratio and finds matching resolution from a skin. No because the code will probably need a fallback in case there is no match, a rare occasion but can happen at some setups, especially on raspberry pis with CRT monitors.
