Renault purchased rear wing signage for the 2010 final Grand Prix IIRC, in addition to the existing engine cover decal, visor decal and overall patch (as above) -- IMO Renault had plenty of visibility, up until Renault-Nissan's own decision to feature Infiniti decals more prominently than Renault decals on Red Bull's car.
That could have been fixed easily for 2016 by replacing Renault-Nissan's Infinti brand with Renault-Nissan's Renault brand as the title sponsor of the Red Bull team, making it "Renault Red Bull Racing" instead of "Infiniti Red Bull Racing" -- note that even with Infiniti as title sponsor, the Renault decal in 2015 is far larger than the Honda decal in 2019. Simply imagine the purple Infiniti livery sections of 2015 replaced with yellow Renault livery sections for 2016 -- without any greater investment on Renault-Nissan's part, Renault-Nissan would have easily achieved greater visibility for the Renault brand.
Instead of this "easy solution", Renault-Nissan decided to buy their own team (back).
Indeed, one wonders (1) if both Renault's and Red Bull's 2016 position were motivated by petty reasons instead of logical and rational reasoning, and (2) whether the partnership of Renault and Nissan is as close and mutually beneficial as such a partnership ought to be, with Renault seemingly upset at the Infiniti branding even though it's all the same company, and that a Infiniti or Datsun sale should be just as worthy to Renault, as a Dacia or Renault sale is to Nissan.
