Yes they are. If you would have individual stealth awareness for enemies in Uncharted, you could play it exactly like Last of us. The progression in the levels is exactly like in uncharted games. You explore tight areas and proceed with automated platforming to the next area with enemies in them.
Its more than stealth. You cannot run and gun like Uncharted. You dont melee people in the same way like you do in Uncharted, You cannot shoot like Uncharted with all the weapon sway. Uncharted has no real time crafting. Basically you cant play the game like you would in uncharted. Even if you want to engage in a pure shootout instead of playing stealthy you have to think about popping your head out of cover etc.. It just does not play like uncharted. Also this game has no platforming. What platforming are you talking about? Uncharted and TLOU are poles apart.
