If you really think the changes to the nose was the key driver to car performance you know very little about subsonic aerodynamics.
reason for the initial noses not working better, and Renault's continuing to work poorly through the year is more to do with how much air is directed over the nose, and how much under the nose. The air directed under the nose will feed the floor and the diffuser (both pressure and suction surfaces).
If your diffuser can handle it, and your front wing can still keep your aero-balance good,
having a higher nose is the more (aerodynamically) effective way to go (see RBR for example).
The two bits in bold are the design drivers. Not the nose.
