Here is my file. I changed the xml to 4K, but I could never get the default.py file adjusted correctly.

I've checked it out and did some digging (as I'm rusty with Kodi related stuff nowadays), here are my findings:
1. The resolution of the screensaver is based on what folder is being used for xbmcgui.WindowXMLDialog - this creates the screensaver's screen.
class xbmcgui.WindowXML(xmlFilename: str, scriptPath: str, defaultSkin: str = 'Default', defaultRes: str = '720p', isMedia: bool = False)[source]
Parameters:
xmlFilename – string - the name of the xml file to look for.
scriptPath – string - path to script. used to fallback to if the xml doesn’t exist in the current skin. (eg xbmcaddon.Addon().getAddonInfo(‘path’))
defaultSkin – [opt] string - name of the folder in the skins path to look in for the xml. (default=’Default’)
defaultRes – [opt] string - default skins resolution. (1080i, 720p, ntsc16x9, ntsc, pal16x9 or pal. default=’720p’)
isMedia – [opt] bool - if False, create a regular window. if True, create a mediawindow. (default=False)

Based on this info the highest resolution is 1080i, 4K doesn't seem to be supported. I've checked around 15 skins and they are all 1080i or 720p.

2. The background needs to have its size defined in the xml as well, it's this part:
<control type="image" id="30020">
            <description>Background</description>
            <posx>0</posx>
            <posy>0</posy>
            <width>1280</width>
            <height>720</height>
            <fadetime>500</fadetime>
            <aspectratio>scale</aspectratio>
        </control>
        <control type="image" id="30022">
            <description>Background</description>
            <posx>0</posx>
            <posy>0</posy>
            <width>1280</width>
            <height>720</height>
            <fadetime>500</fadetime>
            <aspectratio>keep</aspectratio>

3. With current limitations that exist for screensavers, I would need to have an additional folder in resources/skins/Default/, named 1080i, and it would have new xml files that are updated (and tested!!!) on 1080i resolution - I've already seen that some adjustments would need to be made when using 1080i.

4. I've found these and they work from within the screensaver:
xbmcgui.getScreenHeight() - Returns the height of this screen.
xbmcgui.getScreenWidth() - Returns the width of this screen.
I could automate things to start the screensaver in the highest resolution possible - for now it seems that's 1080i - unless you have some better info (again I'm rather rusty).


4 should be relatively easy.
Having a new folder with xmls that need to be reworked and retested sucks big time.
That's the main thing I hated during development, and it's directly connected to the font limitation of screensavers, screensavers are forced to use skin defined fonts, which forces me to have separate xml file for each skin...
