OpenEXR needs a dedicated floating-point pipeline that is not implemented yet.
An EXR may carry named auxiliary channels, multipart images or deep samples, beyond a flat RGB image. A rendered HEIC copy is not an equivalent EXR working file. Channel selection, deep compositing and numeric mapping need explicit engine support; no export of every channel or depth sample is implemented.
EXR can contain multiple image representations with different roles. These are not automatically a timed animation. Selecting an image, preserving a collection or creating several outputs needs explicit engine support; neither a first-image choice nor an all-images export is implemented.
The source can carry HDR information and HEIC has HDR-capable variants. Working radiometric values and display-referred HDR are different representations. Range, primaries, transfer function and signalling must be mapped explicitly; the future engine may instead produce SDR. HDR preservation is not promised by format support.
HEIC commonly uses lossy HEVC; HEVC also has lossless coding tools. Actual quality, bit depth and chroma depend on the encoded profile and settings, not on the .heic extension. HEIC permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
EXR: Typed header attributes, Chromaticities → HEIC: Exif, XMP, ICC, NCLX. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
