Here the channel’s name is inside the name property - but you may use it inside a state too (show state & hide name in the row).
Values of the entity_picture & friendly_name (or state) may be set inside a corresponding template sensor.

Same may be achieved with a conventional entity-row with a bit more card-mod.
