it definitely looks like resin starvation to me.

I agree.

I started the seal coat idea, to ensure a transparent lay-up on the hull and deck exterior.

I don't use a seal coat when glassing the interior deck and hull of my boats.

Glassing in at least 80˚ temperatures, using slow hardeners, small batches, and a roller
give the very thin resin, on the warm wood and glass, the ability to totally displace
all the air surrounding every glass fiber. Using a SOFT squeegee to remove excess resin
won't compress the glass so hard that it bounces back and is resin starved.

If you glassed at lower temperatures with a medium hardener and used a stiff squeegee
I would expect to see the slightly resin starved look of the glass you've shown.

It's not a structural problem but I'd suggest another coat of epoxy to seal the hull surfaces from
further water and dirt intrusion which will break down the glass in years to come.

Without one seal coat, the glass will turn whiter and dirtier over time with exposure to the elements.

Ask me how I know?

Been there.
