The answer could be Yes.

However, the influence depends on what kind of Pt materials and how high the upper potential you used. For pure Pt nanoparticles, the potential cycling below 0,85V_RHE (reversible adsorption for -OH) has little influence, but above 0.85 V (irreversible adsorption, may be Pt-O) has influence on the ECSA. For polycrystalline Pt, the surface is quite sensitive.

For core/shell Pt, such as PtCu/Pt, potential cycling below 0.85 V may influence the ECSA, but the correlation is unclear, depending on how long the new balance will be established during potential cycling.

Cyclic voltammetry is commonly used to estimate the electrochemical active surface area (ECSA) of a catalyst which is required for the estimation of the mass activity. The potential is usually scanned from 0 to 1 volt RHE. At negative or cathodic current density ( 0.05< E < 0.4 in 0.1 HClO3) the reaction is

H (+) + e = H( under-potentially deposited hydrogen)

While at positive (anodic) current (E > 0.6)

2H2O = OH (adsorbed hydroxyl layer) + H3O (+) + e

Pt-O = OH (adsorbed hydroxyl layer)

Since CV is conducted at stagnant conditions, the H (under-potentially deposited hydrogen) peak height and position depend on scan rate. Also the Pt-O = OH (adsorbed hydroxyl layer) peak height and position depend on scan rate. The ECSA which is determined from H (under-potentially deposited hydrogen) depends on Pt-O just as an anodic reaction depends on cathodic reaction.
