The screen rendering went off a cliff, on Windows at least, with LO v5.3.
This is when the rendering engine was changed.

On Windows this caused the aliasing to go from the full-color Cleartype
aliasing to some kind of lesser grayscale-only aliasing.

So on Windows the move to Harfbuzz (BarfHuzz) was a step backwards.

Below I have attached zoomed-in screenshots of your small images.

In the first one from LO v5.1 you can see the colors in the aliasing.

In the second one from LO v6.1 you can see only grayscale.

There was also apparently some change in how the vertical metrics are rendered.
This is why you see changes in the line heights.

You will also see at smaller sizes the characters appear to jump around and
have big gaps between them due to changes in how the hinting is handled.

None of this is documented anywhere that I have found.
You can only discover bits and pieces of what is happening by reviewing
multiple bug reports.
I think some people just don't want to talk about it.

>From what I have seen there currently are no plans to fix this.
The LO fonts rendering "guru" appears to have abandoned the ship when it sank.
