entity_picture URL changed in backend

[cofw2005]

Hello, I recently was trying to make a ESP32 based small screen to show the album artwork playing on the music assistant.
In the debug log, I noticed one thing.

I used a homeassistant text_sensor to obtain the entity_picture attribute from home assistant. When I switch from a playing track to another. I first get an URL and in a few milliseconds get another one.
The first URL is pointing to the last artwork url, and second is the one to new url. Furthermore, they are in different string combinations.
I looked in MA log. I guess I found the reason.
The first URL is generated by metadata.py including provider+image_format+size=500+path. And the second URL is generated by images.py including path+provider+size=0.

In my use case I need to ignore the first one and only download the picture from the second url which is for the new track.

I would like to ask if this is intended, and I was thinking to skip the first one by searching for "fmt=" string or "size=500" string, because new url doesn't contains that. I hope this will be not be changed in future and cause my code issue :)
