any tips / advice / suggestion on how to improve print / reduce or remove gaps.

picture 1:
dome / curve top.

picture 2:
a. 2 shell, 1 shell did not attach properly.
b. 2 shells did not attach properly to infill / top.
c. lots of gaps on inner perimeter top. but inner shells looks ok.
d. minor gaps on inner perimeter.

when inner perimeter are square. there are lesser gaps.

Increase your infill outline overlap percentage by about 20%. I would also increase your top solid layers by +2. Finally, you may also need to increase your extrusion multiplier by ~0.05, but it's hard to tell without more tests.

old over setting : 20-25%
old multiplier : 1.05

new setting :
overlap : 30%
multiplier : 1.10

change a bit infill.
20% / 60% / 100%

100% no gaps, but top layer fells rough. i think too much material.
