Need help with understanding this 3-way wiring setup

I have gone through multiple diagrams on the internet but not able to understand my dining room 3-way switch wiring setup. Any insight or next steps would be helpful.

What do I want to achieve?
I would like to install a 3-way smart dimmer switch that requires a neutral wire. Can I still do that by doing making some adjustments to existing wiring?

What I have?

• Light Fixture
• Switch Box 1
• Switch Box 2

Switch Box 1 has two wire bundles and a 3-way standard switch

• Wire bundle 1 has 2 wires – Black and White
• Wire bundle 2 has 3 wires – Black, Red and White
• White wire of Wire bundle 1 which seems hot connected to the Black wire of Wire Bundle 2 with a wire nut
• Black wire of Wire bundle 1 is connected to the Common screw of Switch 1
• Other two wires of Wire bundle 2 are connected to the Switch 1 (travelers)

Switch Box 2 has 1 wire bundle and a 3-way dimmer switch

• Wire bundle has 3 wires – Black, Red and White
• All three wires are connected to three parts of the 3-way dimmer switch

It goes without saying that there is a ground wire in both switch boxes.

What do I know so far?

• I think Power seems to be getting to the fixture first
• Do not see any neutral wire

What do I not know so far?

• Not sure why the white wire of Wire Bundle 1 in Switch Box 1 is hot?
• Not opened the fixture to see what is in there.

Thank you for your time.
