I do think the layout looks a bit better, nice design here.

This does look a lot nicer than the current design.

I still have a slight fondness for the current layout, but only because of the way it differs from the Splash dialog while this is closely similar. But that is probably just some bias to wanting to show different uses of the new Alert icons. This does look better though.

There is one thing to check and (possibly) address. Apologies that I can't test this at the moment. Of course if you simply increase the user scale this entire dialog will properly increase in size proportionally in all directions. But I am hoping that you can do a test of keeping it at a normal scale but doubling the size of Preferences / Themes / Text Style / (All) Font points. We have some low vision users who use it this way. You will see an doubling of the dialog width while the height will not double, which is expected behavior. But you might want to change the way the logo is scaled if it forces the dialog to get taller than we want (for this accessibility change). So you might decide to have the logo (only) change by UI scale and not by font size, or you might want to limit the upper bound of the scale increase of the logo. Up to you really. We're just trying to support very large fonts on a regular monitor the best we can.
