New naval indeed much better, although...
...as for the main guns, you used the Scharnhorst in the comparison, his sister Gneisenau was during war underway to rearm its main batteries to Bismarck type ones, since both ships were planned for them originally but they took too long so smaller ones were fitted...
HMS Warspite has it's main guns elevation was also modified in modernisation, strongly affecting maximum range.
Japanese built some "light cruisers" in way that would allow them heavy cruiser guns, and replaced them before war as planned.
Some old cruisers have had their armament replaced completely, from old open mounts to new ones, sometimes including replacement for more barrel turrets.
Many UK destroyers had the one turret of main batteries replaced by dual-purpose or AA gun during the war.
That is just few things in mind.
Still, system as you wrote is still by difference of magnitude better than one in HOI2 and also better than one in first HOI. I hope there will be modernisation with micromanagement, taking time to upgrade the ships, possibly depending on severity of modification(new torpedo protection takes probably more time than extra few AA light guns).
