This is NOT AN ENGLISH NAME, the fact that it coincides with an English word is a coincidence and doesn't ruin it because NOT EVERYBODY ON THIS PLANET SPEAKS ENGLISH.
I’ll hazard a guess and say the current meaning of “bland” probably stems from people using it in a sarcastic and/or euphemistic way more often than not. In any case, it’s used almost exclusively as an insult nowadays, synonymous with “boring” or “flavourless”. Maybe in other languages it retained a more positive meaning, but in English, this is more likely to sound like a joke name than anything else.
