[This went to the list instead of to bz -JimC]

That new screenshot confirms that the metrics changed.

pdftocairo and pdftoppm also exibit the anomaly.

mudraw does not seem to.

All use freetype to render the fonts.

But using ftview on the two fonts also shows the cff font darker than
that glyf version.  Unless both are rendered with forced auto hinting.

That strongly suggests that it is a freetype issue.

Try the full fonts side by side in ftview, comparing the hinting modes
and gama.  Either both in the same instance, using n and p to switch
between them, or each in its own ftview.
