The two look nothing alike.......Being from a "Different bit of Forest" is what seperates the many types of Tinctorious, and what leads to the differences between the populations.......Nice pics, but they look much the same as all the standard stock of 'dyeing frogs' at my local fish & reptile store in south west England. here is one we bought saturday...even with the patch of yellow on one leg.....I did pick the one with the black strip down its head as it was different from the others in the tank, which just had plain yellow heads.
Even if these came from a different bit of forest there aren't enough differences to give one group a new name.
I dont think you can use intensity / amounts of colours, or the fact a random pattern of black and yellow misses the head out, to try and create named sub species from what are basically just the normal frog from the wild, for all we know the colours may be vibrant at the moment due to their wild diet, and could potentially fade in long term captivity. Unnecessary naming just feels like someone is trying to create 'brands' for marketing and money making purposes.
