ULTRAVID 10x42 BR, HD and HD-Plus differences (1 Viewer)

Does anyone know the exact difference between the ULTRAVID 10x42 BR, HD and HD-Plus.

As I understand the HD had a HD element in the objective and Hydrophobic lense coatings .
Then the HD-Plus had improved Schott glass prisms to improve light transmission.

I ask because I recently had my original 2002 10x42 BR fully serviced including replacement of objectives costing over £300. I recently tested my binoculars against the HD-Plus and was surprised to find there exactly the same. Even the guy in the shop couldn't tell any visual optical difference or build difference for that matter.
They were identical in optical performance and only different in build by the different HD-Plus badge.
How is that possible ?

Leica updated their coatings a few years ago, so you have new lenses and their latest coatings. this should make the image come close enough to the HD+ that you may not be able to see a difference. My Trinovid HD (2022) IMO comes very close to the HD+ which I used to own.

Thanks I didn't know the coatings had been tweaked..

I am pretty sure I would not have seen any significant difference either. For normal eyes, a freshly serviced BR is as good a binocular as it gets.
