A fully CGI enemy isn't interesting in general over a long term unless you have absolutely amazing effects and a huge budget, and probably Andy Serkis. Grodd works as a big bad in comic form because he's not constrained by those things. On a show, it'll be a constant barrier to write around, with characters rarely interacting face to face, and in those scenes being fairly restricted.
Grodd works on paper, but is not practical and would introduce too many obstacles. At most I see him getting a mini-arc.
And besides, how many serialized shows have introduced a villain and defeated it multiple times and then gone on to make them the big bad, and also be good? Legends of Tomorrow is already struggling with this in Vandal Savage.
