Ignoring parameters such as: Leaf shapes Difference in photosynthetic efficiency due to other metabolic factors Unequal illumination of leaves Nutrient content of the soil Photosynthesis rate of a plant1 depends on the [total number of leaves] × [surface area of a leaf]. Assuming that a tree occupies same ground area as a shrub, there will be same ...

I think you confused between PGA (Phosphoglycerate) and PGAL (phospho glyceraldehyde). The first step of Calvin Cycle is carboxylation where the 5 carbon RUBP is converted to two molecules of 3 carbon PGA (PHOSPHOGLYCERATE) Then comes the second step where two molecules of ATP and 2 molecules of NADPH is used to reduce PGA into PGAL (PHOSPHOGLYCERALDEHYDE) ...

I cannot say anything about the general case, or specifically for day-neutral plants. However, Sforza et al. (2012) have studied the effects of light conditions on algae (used for biofuel production), and their results indicate several problems with continuous light. In continuous light conditions they find lower chlorophyll contents and higher carotenoid ...
